Good question - & I have no answer. Here at Dartmouth, there is only the ICU & a CCU. The ICU is intentionally a mixed MICU/SICU unit. Approx 50% of the attendings are anesthesiologists. The other half is approx an equal mix of IM/Pulm & Surgeons. Due to nature of the structure, all types of attendings & residents cover both med & surg pts. This is why I wanted to to my ICU fellowship here. I do not want my critical care skills limited to one camp or the other.
